ABSTRACT
Title: Investigation of Tensile Johnson-Cook Model Parameters for Nimonic 80A superalloy
Title: Investigation of Tensile Johnson-Cook Model Parameters for Nimonic 80A superalloy
Developing high temperature technology increases the need for high temperature resistant materials. Nimonic 80A alloy is generally preferred due to its high creep resistance, oxidation resistance and high resistance to high temperature corrosion. The study determines the tensile constitutive equation (JC parameters) of Nimonic 80 A superalloys. Johnson Cook (JC) model is preferred amongst the various material constitutve equations (Zerille Armstrong, Bordner Partom, JC model). Three different kinds of tensile experiment were performed to identify the model parameters. These are quasi-static tensile experiments applied at room temperatures. These experiments were carried out at 0.001, 0.01 and 0.1 s-1 strain rates. Therefore, the reference strain rate for all experiments was selected to be 10-3. As a second test, tensile experiments were conducted at room temperature at high strain rates (102 ~ 103 s-1) using the Split Hopkinson pressure bar (SHPB). Lastly, tensile experiments were conducted at high temperatures (300 ~ 900 °C) at 0.001 s-1. It was observed whether all tests are compatible with each other or not, and so five Johnson-Cook (JC) parameters of Nimonic 80 A alloy were identified via the data found from the experiments. After determination of parameters, tensile test simulations by finite element method (FEM) were performed in ANSYS Workbench. As a result, the accuracy of the JC parameters is verified since there is a deviation of %2.84 between the experimental and the simulation results.

ABSTRACT
Title: Optimization of A Heat-driven Thermoacoustic Cooler
Title: Optimization of A Heat-driven Thermoacoustic Cooler
Abstract When an acoustic wave propagates in a narrow tube, a gas in the tube undergoes thermal interactions with the tube wall. As a result, the acoustical energy converts into thermal energy. Using the energy conversion, a heat-driven thermoacoustic cooler can be constructed. In 2002, Yazaki et. al constructed the cooler that consists of a looped tube, an engine stack, and a cooler stack. When the engine stack is differentially heated, the acoustic wave spontaneously generates. The generated acoustic wave travels along the tube and enters the cooler stack. In the stack, the acoustic power is consumed to pump heat from one side the other side of the cooler stack.
Yazaki et. al reported that the performance of it can be improved when the relative position of the stacks is varied. However, they did not measure the performance of the whole system. They also did not perform the optimization. We consider that the performance of Yazaki’s cooler system can be improved by optimizing some important parameters. Therefore, in this investigation, we have optimized the system numerically. We chose five parameters to be optimized; relative position between the stacks, radius of the engine stack, radius of the cooler stack, porosity of the engine stack, and porosity of the cooler stack.
For the numerical optimization, we have used the linier thermoacoustic theory proposed by Rott. In this calculation, the momentum and continuity equations in the Rott’s theory were modified into the transfer matrices. The used transfer matrices were validated using the experimental results. It was found that the transfer matrices used for the calculation has a good agreement with the experimental results. Then, we used the transfer matrices to calculate the performance of Yazaki’s cooler. It was found that the optimum relative position, radius of the engine stack, radius of the cooler stack, porosity of the engine and porosity of the cooler are 0.54, 0.96, 1.06 and 1.3, respectively. In addition, it was found that the numerical optimization of the parameters makes the whole cooler system to be 0.24 of the upper limit value.

ABSTRACT
Title: How UniKL embrace the TVET challenges
Title: How UniKL embrace the TVET challenges
Technical and Vocational Education and Training (TVET) will play a pivotal role in providing the skilled workforce required for Malaysia’s economic transformation and the next stage of the country growth. It is the pathway of the 21st century, the way forward to close gaps between economies of the globe, and vital to meet the demands of a technologically complex and unique future. However, recent feedback showed a gap between supply and demand as the industry complains that training providers do not provide adequate skill and knowledge to run the operation. In the meantime, the training providers complains the industry do not employ their graduates or pay them under average salary. The decreasing of student intake related to TVET courses also significantly affect the TVET future. In this sharing, the researchers would like to share how UniKL identify the main course of the problem and take the initiative to achieve the TVET vision by proposing higher-TVET via engineering programs.

Title: Issues and challenging on Malaysia’s TVET: A study on the industrial’s prerequisites
Human capital development is a critical factor in generating and sustaining Malaysia's economic growth. Malaysia
dealing with the issues of unemployment among university graduates. By starting a skills training program, the government has trying to strengthen the skills of graduates so that they are able to get professional positions. However, there is lacking information on the right and appropriate assessment and evaluation of studies with respect to employability skills training programs local to help unemployed university graduates. This study is to identify the appearances of industries need of TVET in improving the best skills employability to the graduates in Malaysia. This research will use the statistical techniques and descriptive method and 255 questionnaires were distributed to the Malaysian Industries in Northern Region. Finally the results of the study have policy implications where it can help for the development of effective strategies in improving the efficiency of TVET programs. The importance of this study will be able to provide specific policy guidelines for policy implications for strategy development.
